PCI and PCI-E add on cards with parallel port that work out of the box

I know Tom has already tested this chipset, but I'll add some more details.

Model: PAR6408AXX100
Chipset: Sunix SUN2212
Interface: PCIe
Supports PS/2: YES
Supports EPP: NOT TESTED
Supports IN Mode: YES (In PS/2 Mode)
Supports X Mode: YES (In PS/2 Mode - Control port pins are open drain/collector)
Tested OS: linuxcnc-2.8.4 / Debian Buster
Tested Computer: Dell Optiplex 760





For IN and X Modes to work, mode has to be set to PS/2.

I couldn't figure out why, but a couple of times during my testing the mode changed itself to Standard Mode, whitch is not bi-directional. If one tries to use IN or X modes while in Standard Mode some pins won't work. 

Does anyone know what may be causing the ECR register to randomly reset to Standard Mode (0b000XXXXX) ? If I can't find a way to fix it I am thinking of setting a startup script to make sure the right mode is always in place.

Model: Naxos NX1PAR-PCI
Chipset: Moschip MCS9805CV
Interface: PCI
Supports PS/2: YES
Supports EPP: NOT TESTED
Supports IN Mode: YES (In PS/2 Mode)
Supports X Mode: YES (In PS/2 Mode - Control port pins are open drain/collector)
Tested OS: linuxcnc-2.8.4 / Debian Buster
Tested Computer: Dell Optiplex 760

What's the PCI ID of this card, that's the secret source.

With regards to the second port, you'll have to check how the second parallel port is enabled, some chipsets use strapping or use a eeprom for the config.
If you aren't getting the address of the second parallel port come up adding the connector and resistors may not enable it.
Find the data sheet first and work out how to config the chip first before getting out the soldering iron.

You are right!

I tried to read the registers with the remaning adresses and it didn't work.  



I tried both Base/Extended ccd8/cce0 and cce0/cce8. Didn't work. They must be strapped, as you said.

Thank you very much for the tip!
